Everything about Antarctic ocean animals.
Borders and names for oceans and seas were internationally agreed when the International Hydrographic Bureau (IHB), the precursor to the IHO, convened the First International Conference on 24 July 1919. The IHO then published these in its Limits of Oceans and Seas, the first edition being 1928. Since the first edition, the limits of the Southern Ocean have moved progressively southwards; since 1953, it has been omitted from the official publication and left to local hydrographic offices to determine their own limits. The IHO included the ocean and its definition as the waters south of 60°S in its year 2000 revisions, but this has not been formally adopted, due to continuing impasses over other areas of the text, such as the naming dispute over the Sea of Japan. The 2000 IHO definition, however, was circulated in a draft edition in 2002 and is used by some within the IHO and by some other organizations such as the US Central Intelligence Agency and Merriam-Webster. [note 5] Australian authorities regard the Southern Ocean as lying immediately south of Australia. The National Geographic Society does not recognize the ocean, depicting it (if at all) in a typeface different from the other world oceans; instead, it shows the Pacific, Atlantic, and Indian Oceans extending to Antarctica on both its print and online maps. [note 6] Map publishers using the term Southern Ocean on their maps include Hema Maps and GeoNova.
